More on this here , as well as some audio examples for you to listen to. For example, some of that brainy tissue needed to be a singing, territory defending, mate seeking male bird is added during breeding season, and removed later when not needed. And the more the juveniles paid attention, the better they learned. Here’s the problem.

He then says he goes to "exceptional lengths" to make ensure the physical and psychological welfare of the primates he uses, "except when it's absolutely necessary" to harm them. And then comes a brief conversation about Singer and how we wouldn't use young humans, which Jentsch says is precisely why we should use primates.

The active colonies of wasps are efficient protection against primates and large avian predators. Here are a few examples: The Ostrich Communal Nesting System. The benefit for the wasps is that they get to keep a beautiful pet. Think about it when you feel hard done by life.

Flight has evolved multiple times; it has emerged in lizards, snakes, fish, bats, maybe bats again, distant relatives of primates, regular primates, rodents, and a few other unlikely taxa, in a rather half baked fashion, not “true” flight. It has evolved in non-vertebrate animals like insects more than once.

For example, you could say, “among mammals, only three families include species with a meaningful degree of root eating” or “within the family that includes lemmings and voles, there is a mixture of monogamous and polygynous species” and so on. That was useful, and it is still useful, even if there are often major exceptions.

Primates are exceptional among the mammals, living amphibians (which represent only a small part of the original amphibian family tree) are pretty noisy too. Song birds use the two pipes in the lower part of the syrinx differently to make more complex sounds, for example. Fish are mostly silent on the matter.

Flight is an example. For instance, in primate phylogeny, postcranial traits (bony traits of the body, not the head) are usually useless because we can’t link teeth to bodies in most cases, and the teeth drive the taxonomy (though there are some recent exceptions ). This requires a few things to be true, depending on the fossils.

There are probably other major trends that depend, for example, on latitude and timing. For instance, I can lay my hands on data for primates and rodents (because I’ve collected those data for research) but I don’t have comparable data for bovids (just selected data) and zero data for birds (in spreadsheets on my computer).

The Ashy Tailorbird is a good example of the different perspectives of describing a bird – while the English name focuses on the body of the bird, the Latin species name ruficeps refers to the rufous head. The paper cites the example of the Blue-footed Booby: Its foot color becomes duller when the birds are malnourished.
